Mechanical Engineering Manager

We are looking for a motivated Mechanical Engineering Manager to lead a team of engineers developing cutting-edge products and technologies for military, governmental, and commercial customers. This role combines technical leadership, project ownership, mentorship, and hands-on engineering.

Our engineers drive projects from concept through production, working across design, analysis, prototyping, testing, and manufacturing. The Mechanical Engineering Manager will provide technical direction, mentor engineers, oversee project execution, and help solve challenging real-world engineering problems while remaining engaged in the technical work.

Our R&D spans a wide range of technologies, including advanced HVAC systems, engine electrification, robotics, additive manufacturing, hypersonic vehicle components, laser weapon cooling, and more. No two days are the same, and this role offers significant opportunity to influence the direction of both our engineering team and future R&D efforts.
